Namespace Partitions

A namespace is the tree of all data in the directory, synonymous with directory information tree. It is defined by the DN of the top node in the tree.

A namespace partition is a sub-section of the directory information tree. (The partition might cover the whole namespace.)

Each DSA serves a namespace partition. When a namespace is partitioned to be served by more than one DSA, the directory is said to be distributed. A well distributed directory provides good scalability and performance.

You can control each namespace partition separately. Each partition can have different security and can be located on a different set of hosts than other namespace partitions.

If more than one DSA serves the same namespace partition, the partition is said to be replicated.

DXmanager represents namespace partitions using the following icons:

• Replicated namespace:
• Unreplicated namespace:
